An air gap is an extreme security measure where a computer or network is physically disconnected from all other networks to prevent remote attacks. This technique is used for highly sensitive systems, such as those controlling critical infrastructure.

There is no single "magic bullet" for security. An effective strategy uses multiple layers of defense. If one layer fails, another may still stop the attack. This combination of technology, processes, and people provides the most robust protection.

The allow list is used to tell your antivirus or security software not to scan or block specific items that you know are safe. This is useful for preventing false positives on legitimate software that may exhibit unusual behavior.

Authentication is the process of verifying a user's identity to ensure they are who they claim to be. This is typically done with credentials like usernames and passwords, or through other methods like MFA or biometrics.

The International Organization for Standardization (ISO) develops various standards, including those for information security management systems (e.g., ISO/IEC 27001). These standards provide a framework for organizations to manage and protect their information assets.

Biometric authentication verifies a person's identity based on unique physiological (e.g., fingerprints, facial features) or behavioral (e.g., voice, gait) characteristics. It's 'something you are'.

Disabling all security systems is a highly risky and illogical action that would exacerbate an incident, not resolve it. A robust incident response plan focuses on systematic steps to prepare for, detect, contain, eradicate, recover from, and post-analyze security incidents.

Outdated software often contains known security vulnerabilities that have been discovered and publicly disclosed. If these vulnerabilities are not patched through updates, attackers can easily exploit them to gain unauthorized access or cause damage.

A man-in-the-middle (MITM) attack involves an attacker intercepting communication between two parties without their knowledge, allowing the attacker to eavesdrop on, or even alter, the communication.

Tokenization is a data security technique where sensitive data (e.g., credit card numbers) is replaced with a randomly generated, non-sensitive equivalent (a token). This token can then be used in systems without exposing the original sensitive data, enhancing security and reducing compliance scope.
